Nineteen racehorses have been studied for haemorheologic factors as earlier studies showed a definite correlation between physical fitness and these factors in humans. Results included individual values for all viscosity factors, and the arithmetic means, the latter showing 4.70 +/- 0.49 cP for blood viscosity measured at a shear rate of 180 s-1; 1.100 +/- 0.048 cP for plasma viscosity; 1.045 +/- 0.063 for the rigidity of red cells defined by term 'Tk'; 42.2 +/- 4.1% haematocrit; 290 +/- 39 mg per 100 ml for fibrinogen level; and 278 +/- 75 mm h-1 for aggregation of red cells at 37 degrees C (corrected for plasma viscosity and at constant haematocrit of 30%). Data for subgroups have also been obtained. Linear regressions of apparent blood viscosity against log shear rate were found to be specific to individual racehorses, and differed significantly between some racehorses. Data for blood viscosity, plasma viscosity and haematocrit were near the values reported for human athletes, but rigidity of red cells and aggregation of red cells was found to be much higher in horses. No correlation was found between aggregation of red cells and fibrinogen level. In blood samples from some horses, the erythrocyte sedimentation rates increased with decrease of temperature, while in other samples they increased with increase of temperature. It appears that it is possible to characterise individual horses by blood viscosity factors and viscosity functions.
由于早期研究表明人类的身体健康与血液流变学因素之间存在明确的相关性，因此对19匹赛马的血液流变学因素进行了研究。结果包括所有粘度因素的个体值以及算术平均值，后者显示在剪切速率为180 s-1时测量的血液粘度为4.70±0.49 cP；血浆粘度为1.100±0.048 cP；由术语“Tk”定义的红细胞刚性为1.045±0.063；血细胞比容为42.2±4.1%；纤维蛋白原水平为每100 ml 290±39 mg；以及在37摄氏度时红细胞聚集为278±75 mm h-1（校正血浆粘度并在血细胞比容恒定为30%时）。还获得了亚组的数据。发现表观血液粘度与对数剪切速率的线性回归特定于个体赛马，并且在一些赛马之间存在显著差异。血液粘度、血浆粘度和血细胞比容的数据接近人类运动员报告的值，但发现马的红细胞刚性和红细胞聚集要高得多。未发现红细胞聚集与纤维蛋白原水平之间存在相关性。在一些马的血液样本中，红细胞沉降率随温度降低而增加，而在其他样本中则随温度升高而增加。看来有可能通过血液粘度因素和粘度函数来表征个体马匹。
